Demonstrated by some typical application examples in the analysis of Chinese traditional Medicines. Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 195-205 (1991). Some application examples of using quantitative thin-layer chromatography for the analysis of pharmaceutical products, especially of Chinese traditional medicinal materials are presented. 1) TLC of coptis (goldthread) on silica with ethyl acetate - methanol - chloroform - ethylendiamine - water 80:25:2:6:6. Determination by fluorescence densitometry at 365/>400 nm. 2) TLC of ginsenoides (from various varieties of ginseng) on silica with chloroform - methanol - water 65:35:10. Densitometry by absorbance at 525 nm after spraying with 10% sulfuric acid in chloroform and heating for 30 min at 105 °C. 3) TLC of styrax, boswellia and aplotaxis lappa on silica with petrol ether - hexane - methyl acetate - formic acid 10:30:15:1.
